Skippy,
All the info is on their site at phaseperfect.com, check it out.
I got a Model DPC A10, 30a output, reccomended single phase input circuit breaker, 60a to 70a. I've got it on a 50a and use it with a 7hp spindle machine. Again the performance and quality doesn't come cheap, about $2600
Not something you would use for a single motor, unless you really love that motor!
